在 Chrome Docker 容器中使用 Selenium 的 SessionNotCreated

Question

我使用 Selenium 创建了一个 .Net 应用程序。本地一切工作正常，但是当在 Docker 容器中使用我的应用程序时，我总是收到以下异常

System.InvalidOperationException: session not created: Chrome failed to start: exited normally.
        (chrome not reachable)
        (The process started from chrome location /usr/bin/google-chrome is no longer running, so ChromeDriver is assuming that Chrome has crashed.) (SessionNotCreated)
         at OpenQA.Selenium.WebDriver.UnpackAndThrowOnError(Response errorResponse, String commandToExecute)
         at OpenQA.Selenium.WebDriver.ExecuteAsync(String driverCommandToExecute, Dictionary`2 parameters)
         at OpenQA.Selenium.WebDriver.Execute(String driverCommandToExecute, Dictionary`2 parameters)
         at OpenQA.Selenium.WebDriver.StartSession(ICapabilities capabilities)
         at OpenQA.Selenium.WebDriver..ctor(ICommandExecutor executor, ICapabilities capabilities)
         at OpenQA.Selenium.Chromium.ChromiumDriver..ctor(ChromiumDriverService service, ChromiumOptions options, TimeSpan commandTimeout)
         at OpenQA.Selenium.Chrome.ChromeDriver..ctor(ChromeDriverService service, ChromeOptions options, TimeSpan commandTimeout)
         at OpenQA.Selenium.Chrome.ChromeDriver..ctor(ChromeOptions options)

在 .Net 应用程序中创建 Chrome 驱动程序时，我使用以下参数

 var chromeOptions = new ChromeOptions();
        if (OperatingSystem.IsLinux())
        {
            chromeOptions.BinaryLocation = "/usr/bin/google-chrome"; // Set the correct path to the Chrome binary
        }

        chromeOptions.AddArgument("--disable-dev-shm-usage");
        chromeOptions.AddArgument("--no-sandbox");
        chromeOptions.AddArgument("--disable-search-engine-choice-screen");
        _webDriver = new ChromeDriver(chromeOptions);

我正在使用 Selenium Chrome 图像，而它包含我的 .Net 应用程序，该应用程序作为独立发布。

我在尝试在本地运行容器的云上都遇到了这个问题。
